Lindsay Lohan Knife Pics Could Cost Vanessa Minnillo Millions

Celebrity snoops are dishing that the mystery brunette posing seductively with a knife in Lindsay Lohan’s now in-famous faux throat-slashing photos is former Miss. Teen USA Vanessa Minnillo (that’s debatable), and the tabs are speculating that the former “Entertainment Tonight” correspondent and “TRL” DJ may have a tough time dying down the bad press.

ET roducers flew VM to Los Angeles to cover the Grammys, “she was extremely high maintenance,” said one source. “She insisted they fly her own hair and makeup people and her personal assistant out with her every time she flew to L.A. She only flew first class and stayed at the Four Seasons, and then she didn’t want to work.”

“Vanessa wants to be a celebrity, not interview them,” said the source. “She wouldn’t conduct post-show interviews because she wanted to party. She expected to be paid a full-time salary for a part-time job.”

A pushy Minnillo has been known to bark orders at cocktail waitresses and cause scenes when she goes club hopping at night.

Vanessa’s rep denies any “diva behavior” and told Page Six, “She chose to leave ‘ET’ because her contract ended. This is the first I’ve heard about any bad behavior.”
